9. "Why," He says, "do ye not understand my speech? Even because ye cannot hear my word." And so they could not understand, because they could not hear. And whence could they not hear, but just because they refused to be set right by believing? And why so? "Ye are of your father the devil." How long do ye keep speaking of a father? How often will ye change your fathers,--at one time Abraham, at another God? Hear from the Son of God whose children ye be: "Ye are of your father the devil."
10. Here, now, we must beware of the heresy of the Manicheans, which affirms that there is a certain principle of evil, and a certain family of darkness with its princes, which had the presumption to fight against God; but that God, not to let His kingdom be subdued by the hostile family, despatched against them, as it were, His own offspring, princes of His own [kingdom of] light; and so subdued that race from which the devil derives his origin. From thence, also, they say our flesh derives its origin, and accordingly think the Lord said, "Ye are of your father the devil," because they were evil, as it were, by nature, deriving their origin from the opposing family of darkness. So they err, so their eyes are blinded, so they make themselves the family of darkness, by believing a falsehood against Him who created them. For every nature is good; but man's nature has been corrupted by an evil will. What God made cannot be evil, if man were not [a cause of] evil to himself. But surely the Creator is Creator, and the creature a creature [a thing created]. The creature cannot be put on a level with the Creator. Distinguish between Him who made, and that which He made. The bench cannot be put on a level with the mechanic, nor the pillar with its builder; and yet the mechanic, though he made the bench, did not himself create the wood. But the Lord our God, in His omnipotence and by the Word, made what He made. He had no materials out of which to make all that He made, and yet He made it. For they were made because He willed it, they were made because He said it; but the things made cannot be compared with the Maker. If thou seekest a proper subject of comparison, turn thy mind to the only-begotten Son. How, then, were the Jews the children of the devil? By imitation, not by birth. Listen to the usual language of the Holy Scriptures. The prophet says to those very Jews, "Thy father was an Amorite, and thy mother a Hittite." [781] The Amorites were not a nation that gave origin to the Jews. The Hittites also were themselves of a nation altogether different from the race of the Jews. But because the Amorites and Hittites were impious, and the Jews imitated their impieties, they found parents for themselves, not of whom they were born, but in whose damnation they should share, because following their customs. But perhaps you inquire, Whence is the devil himself? From the same source certainly as the other angels. But the other angels continued in their obedi ence. He, by disobedience and pride, fell as an angel, and became a devil.
11. But listen now to what the Lord says: "Ye," said He, "are of your father the devil, and the lusts of your father ye will do." This is how ye are his children, because such are your lusts, not because ye are born of him. What are his lusts? "He was a murderer from the beginning." This it is that explains, "the lusts of your father ye will do." "Ye seek to kill me, a man that telleth you the truth." He, too, had ill-will to man, and slew man. For the devil, in his ill-will to man, assuming the guise of a serpent, spoke to the woman, and from the woman instilled his poison into the man. They died by listening to the devil, [782] whom they would not have listened to had they but listened to the Lord; for man, having his place between Him who created and him who was fallen, ought to have obeyed the Creator, not the deceiver. Therefore "he was a murderer from the beginning." Look at the kind of murder, brethren. The devil is called a murderer not as armed with a sword, or girded with steel. He came to man, sowed his evil suggestions, and slew him. Think not, then, that thou art not a murderer when thou persuadest thy brother to evil. If thou persuadest thy brother to evil, thou slayest him. And to let thee know that thou slayest him, listen to the psalm: "The sons of men, whose teeth are spears and arrows, and their tongue a sharp sword." [783] Ye, then, "will do the lusts of your father;" and so ye go madly after the flesh, because ye cannot go after the spirit. "He was a murderer from the beginning;" at least in the case of the first of mankind. From the very time that murder [manslaughter] could possibly be committed, he was a murderer [manslayer]. Only from the time that man was made could manslaughter be committed. For man could not be slain unless man was previously made. Therefore, "he was a murderer from the beginning." And whence a murderer? "And he stood [abode] not in the truth." Therefore he was in the truth, and fell by not standing in it. And why "stood he not in the truth"? "Because the truth is not in him;" not as in Christ. In such a way is the truth [in Him], that Christ Himself is the Truth. If, then, he had stood in the truth, he would have stood in Christ; but "he abode not in the truth, because there is no truth in him."
12. "When he speaketh a lie, he speaketh of his own: for he is a liar, and the father of it." [784] What is this? You have heard the words of the Gospel: you have received them with attention. Here now, I repeat them, that you may clearly understand the subject of your thoughts. The Lord said those things of the devil which ought to have been said of the devil by the Lord. That "he was a murderer from the beginning" is true, for he slew the first man; "and he abode not in the truth," for he lapsed from the truth. "When he speaketh a lie," to wit, the devil himself, "he speaketh of his own;" for he is a liar, and its [his] father." From these words some have thought that the devil has a father, and have inquired who was the father of the devil. Indeed this detestable error of the Manicheans has found means down to this present time wherewith to deceive the simple. For they are wont to say, Suppose that the devil was an angel, and fell; and with him sin began as you say; but, Who was his father? We, on the contrary, reply, Who of us ever said that the devil had a father? And they, on the other hand, rejoin, The Lord saith, and the Gospel declares, speaking of the devil, "He was a murderer from the beginning, and abode not in the truth, because there is no truth in him. When he speaketh a lie, he speaketh of his own: for he is a liar, and his father."
13. Hear and understand. I shall not send thee far away [for the meaning]; understand it from the words themselves. The Lord called the devil the father of falsehood. What is this? Hear what it is, only revolve the words themselves, and understand. It is not every one who tells a lie that is the father of his lie. For if thou hast got a lie from another, and uttered it, thou indeed hast lied in giving utterance to the lie; but thou art not the father of that lie, because thou hast got it from another. But the devil was a liar of himself. He begat his own falsehood; he heard it from no one. As God the Father begat as His Son the Truth, so the devil, having fallen, begat falsehood as his son. Hearing this, recall now and reflect upon the words of the Lord. Ye catholic minds, consider what ye have heard; attend to what He says. "He"--who? The devil--"was a murderer from the beginning." We admit it,--he slew Adam. "And he abode not in the truth." We admit it, for he lapsed from the truth. "Because there is no truth in him." True: by falling away from the truth he has lost its possession. "When he speaketh a lie, he speaketh of his own: for he is a liar, and the father of it." He is both a liar, and the father of lies. For thou, it may be, art a liar, because thou utterest a lie; but thou art not its father. For if thou hast got what thou sayest from the devil, and hast believed the devil, thou art a liar, but not the father of the lie. But he, because he got not elsewhere the lie wherewith in serpent-form he slew man as if by poison, is the father of lies just as God is Father of truth. Withdraw, then, from the father of lies: make haste to the Father of truth; embrace the truth, that you may enter into liberty.
14. Those Jews, then, spake what they saw with their father. And what was that but falsehood? But the Lord saw with His Father what He should speak; and what was that, but Himself? What, but the Word of the Father? What, but the truth of the Father, eternal itself, and co-eternal with the Father? He, then, "was a murderer from the beginning, and abode not in the truth, because there is no truth in him; when he speaketh a lie, he speaketh of his own, for he is a liar,"--and not only a liar, but also "the father of it;" that is, of the very lie that he speaks he is the father, for he himself begat his lie. "And because I tell you the truth, ye believe me not. Which of you convicteth me of sin," as I convict both you and your father? "If I say the truth, why do ye not believe me," but just because ye are the children of the devil?
15. "He that is of God heareth God's words: ye therefore hear them not, because ye are not of God." Here, again, it is not of their nature as men, but of their depravity, that you are to think. In this way they are of God, and yet not of God. By nature they are of God, in depravity they are not of God. Give heed, I pray you. In the gospel you have the remedy against the poisonous and impious errors of the heretics. For of these words also the Manicheans are accustomed to say, See, here there are two natures, [785] --the one good and the other bad; the Lord says it. What says the Lord? "Ye therefore hear me not, because ye are not of God." This is what the Lord says. What then, he rejoins, dost thou say to that? Hear what I say. They are both of God, and not of God. By nature they are of God: by depravity they are not of God; for the good nature which is of God sinned voluntarily by believing the persuasive words of the devil, and was corrupted; and so it is seeking a physician, because no longer in health. That is what I say. But thou thinkest it impossible that they should be of God, and yet not of God. Hear why it is not impossible. They are of God, and yet not of God, in the same way as they are the children of Abraham, and yet not the children of Abraham. Here you have it. It is not as you say. Hearken to the Lord Himself; it is He that said to them, "I know that ye are the children of Abraham." Could there be any lie with the Lord? Surely not. Then is it true what the Lord said? It is true. Then it is true that they were the children of Abraham? It is true. But listen to Himself denying it. He who said, "Ye are the children of Abraham," Himself denied that they were the children of Abraham. "If ye are Abraham's children, do the deeds of Abraham. But now ye seek to kill me, a man that telleth you the truth, which I have heard from God: this did not Abraham. Ye do the works of your father," that is, of the devil. How, then, were they both Abraham's children, and yet not his children? Both states He showed in them. They were both Abraham's children in their carnal origin, and not his children in the sin of following the persuasion of the devil. So, also, apply it to our Lord and God, that they were both of Him, and not of Him. How were they of Him? Because He it was that created the man of whom they were born. How were they of Him? Because He is the Architect of nature,--Himself the Creator of flesh and spirit. How, then, were they not of Him? Because they had made themselves depraved. They were no longer of Him, because, imitating the devil, they had become the children of the devil.
